Abstract
It is intended to reduce the number of exclusive signal interconnections for connecting a host module to a liquid crystal display driver for a sub-display, and peripheral devices, respectively. A liquid crystal display drive and control device comprises, over one semiconductor substrate, a host interface circuit, a drive circuit, and an output port. The host interface circuit is used for connection with the host module. The drive circuit generates a drive signal for driving a liquid crystal display on the basis of information inputted to the host interface circuit before outputting. The output port is capable of controlling a logic level of an output signal on the basis of the information inputted to the host interface circuit. The liquid crystal display drive and control device is capable of performing the function of distributing signals to circuits subjected to control by level signals with determined logic levels, respectively, such as strobe control of a liquid crystal display driver for a sub-display, control of peripheral devices including a camera flashlight, and so forth.
